Abstract

Physicochemical methods are used to study the phase equilibria during crystallization of alloys in the Al2O3–HfO2–La2O3 system for the first time. Liquidus and solidus projections onto the concentration triangle and melting diagram and crystallization scheme are constructed. No new ternary compounds and appreciable ranges of ternary solid solutions are found in the system.
